Are there any galaxies that have travelled faster than the speed of light?
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
Will you move into another galaxy?
Not in the near future. Other galaxies are hundreds of thousands, or millions, of light-years away; travelling at the speed of light, it would thus take millions of years to travel to most galaxies; travelling at a lower speed would, of course, take longer.Not in the near future.

What is the maximum recession velocity of the galaxy observed?
Some of the furthest galaxies are believed to be "travelling" faster than the speed of light. They are not actually "travelling" faster than the speed of light, but creating space, faster than the speed of light.
What is an airspeed?
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
What is the medium of speed traveling through air?
Air is the medium (if you are talking about something travelling through it).
Velocity of sound depends on?
The medium through which it is propagating. For exampl if the sound waves are travelling in air they will move slower than those travelling through a wall speed of sound in solids > speed of sound in liquids > speed of sound in gases
What is the speed of sound travelling through glass?
It is approx 4540 metres/second
Is it Mach or times the speed of sound?
Mach is the speed of an object expressed as a multiple of the speed of sound in the same medium. Thus, an object travelling at 686 metres per second through air, at sea level, is travelling at Mach 2 because sound would travel through it at 343 m/s. However, it the object was travelling under water at the same speed then it would be travelling at approx Mach 0.46 since sound travels at 1484 m/s through water.
What can speed up light?
Travelling through a medium that is optically less dense. Vacuum is best.
What is Mach 1 and 2?
The Mach number of an object travelling through a fluid is its speed relative to the speed of sound travelling through the same medium. So an aircraft flying at Mach 1 at sea level would be travelling faster than an aircraft flying at Mach 1 at a high altitude (where the air is thinner and sound travels slower). An object travelling at Mach 2 is travelling twice as fast as an object travelling through the same fluid under the same conditions (temperature and pressure). BUT In common usage, Mach 1 is the speed of sound in air, at sea level and 20 deg C.
What happens to the speed of the light as it travels from the air through the glass and then through the water?
The light refracts due to the change in speed. The change in speed occurs because the light is travelling through a denser medium. So it will travel fastest through the air and slowest through the glass
Do speed of light depends on some factors as speed of sound depends on temperature?
Yes. It depends on the refractive index of the medium through which the light is travelling.
